i usually never test my water that i make up for water changes, i have been assuming that the levels are where they should be. silly me.

lately i have noticed my magnesium climbing higher and higher and today i tested it at 2000 ppm. now i know that oceanpure has high magnesium, usually around 1600 ppm, but that would not explain my high magnesium.

I have also had problems maintaining my alkalinity lately, so i finally checked the ocean pure. 2300 ppm magnesium. 6 dKH. pH 8.3. 350 ppm calcium.

so i went to golds and got a bag of reefcrystal since i used to use it about 6 months ago. 1400 ppm magnesium, 400 ppm Ca and 10 dKH. pH 8.3. thats more like it.

anyone else experience this with oceanpure?
